CHARLES B. YOUNG AND CHARLES J. CASPAR, OF PITTSBURGH, PENNSYLVANIA, AS-SIGNO'RS TO PITTSBURGH PLATE GLASS COMPANY, A CORPORATION OF PENN-SYLVANIA.

Application filed September 24, 1921. Serial No. 502,981.

To aZZ whom it may concern:

Be it known that we, CHARLES B. YOUNG and CHARLEs- J. CAsPAR, citizensof the United States of America, and residing at Pittsburgh, in thecounty of Alleghen and State of Pennsylvania, have invente certain newand useful Improvements in Store- Front Constructions, of which thefollowing is a specification.

The invention relates'to store front construction and particularly tothe corner and division bars. It has for itsobjects the simplificationand cheapening of corner and division bar construction, and theprovision of one in which the labor of installation is reduced to aminimum. Certain embodiments of the invention are illustrated in theaccompanying drawings, wherein:

Figure 1 is a horizontal section through the improved store frontconstruction. Fig.

2 is an enlarged detail section through the frontstrip and one of theholding clips mounted thereon. Fig. 3 is a plan view of a modified formof bolt and clip construction. Fig. 4 is a view similar to that of Fig.3 of a modified construction. And Figs. 5 and 6 are sectionsthroughmodified'types of front strips involving the use of dove-tails ofdifferent cross section.

Referring first to Fig. '1, the reference numerals 1, 2, 3, 4 and 5designate sheets of glass to which a store front construction isapplied. Referring to the corner bar construction at the left of Fig. 1,6 is the outside or front strip and 7 is the inside or back strip, bothof such strips being formed of sheet metal, the back stri being providedat suitable intervals with perforations to receive the securing bolts 8.The front strip 6 is bent inward at its center to provide the dove-tailportion 9. The bends in the metal are arranged so that the crackextending along the front side of the strip at the opening into thedove-tail is of very slight width, the curved portions of the metalpractically coming into contact at this point. The dove-tail portion 9is engaged by a series of clips 10 slidably mounted on the portion 9 andbeing held in adjusted position by means bolts 8 which are threadedthrough the clips at their forward portions so that on rotating thebolts a clamping pressure is applied to hold the clips in any osition towhich they may be adjusted.

he rear ends of the bolts are also threaded and are engaged by nuts 11,such nuts being preferably of the conical form illustrated and extendingpartially through the perforations in the back strip 7. The constructionat the division bar located at the right of the corner bar justdescribed is similar to that of the corner bar except that the front andback strips 12 and 13 are shaped somewhat differently to conform to thelocation of the device as a division bar. WVhen it is desired to use astiffener at this point the channel member 13 is employed, such channelmember being of sheet metal and being held in place by the transversebolts 14. The clips and securing bolts are the same as above describedin connection with the corner bar.

The construction of the division bar at the right of that just describedillustrates the application of the principle where a connection is to bemade to another sheet of glass 15. In this construction the back strip16 has a dove-tail portion 17 which is engaged by a pair of clip members18 provided at their inner ends with the semi-circular parts 19 and heldin position bythe bolts 20. The sheet 15 is secured to the parts 19 bythe grip members 20 held by the bolts'21 and provided at their rearsides with the gripping edges 22 engaging the opposite sides of thesheet 15.

The corner bar construction at the extreme right of Fig. 1 is thesame-as that of the corner bar previously described except that theinner and outer strips 23 and 24 are differently shaped to fit thedifference in location. The clips and holding bolt constructions are thesame as those heretofore described in connection with other parts of theconstruction.

Fig. 3 illustrates a modified form of clip and bolt construction inwhich the clip members 25 are made integral with the bolt 26, theforward end of the bolt being slotted as indicated at 27. The portion ofthe bolt to the rear of the clips is threaded and carries a nut 28. Thedistance between the clips 25 is such that when the device is fittedover a dove-tail portion like the portion 9 of Fig. 1, the clip may beslipped along to its desired position, after which the tightening of thenut 28 holds the device in its adusted position.

Fig. 4 illustrates a modification of the construction of Fig. 3 whereinthe slot 27 of Fig. 3 is extended throughout the length of the bolt,thus providing the two similar parts 29. These parts may be fitted overa dove-tail and clamped in position by applying the nut 30.

Figs. 5 and 6 illustrate two different forms of front strips 30 and 31,such strips differing from those of Fig. l in the matter of thedove-tail portions 32 and 33. This construction is similarly applicableto use in connection with corner bars following the arrangementillustrated in Fig. 1. In all cases the dove-tail part of the bar, inaddition to its function of holding the clips, has the further importantfunction of giving a large degree of stiffness to the bars.

W hat we claim is:

1. In combination in a store front construction, a pair of glass sheetshaving their edges in opposition but spaced apart, a front strip ofsheet metal having its side edges in engagement with the front faces ofthe glass sheets and having a central dove-tail portion convergingforwardly lying in the space between the edges of the sheets to the rearof said side edges and opening forwardly, a back strip also of sheetmetal having its edges engaging the rear faces of the glass sheets andprovided at intervals with perforations, and holding bolts extendingthrough the perforations and provided with holding clips fitting aroundthe converging sides of said dove-tail portion of the front strip andadjustable along such front strip.

2. In combination in a store front construction, a pair of glass sheetshaving their edges in opposition but spaced apart, a front strip ofsheet metal having its side edges in engagement with the front faces ofthe glass sheets and having a central dove-tail portion convergingforwardly lying in the space between the edges of the sheets to the rearof said side edges and opening forwardly, a back strip also of sheetmetal having its edges engaging the rear faces of the glass sheets andprovided at intervals with perforations, holding bolts extending throughthe perforations and provided with holding clips fitting around theconverging sides of said dove-tail portions of the front strip andslidable longitudinally thereon, and means whereby the clips are clampedagainst longitudinal movement on the dovetail portion.

3. In combination in a store front construction, a pair of glass sheetshaving their edges in opposition but spaced apart, a. front strip ofsheet metal having its side edges in engagement with the front faces ofthe glass sheets and having a central dove-tail portion convergingforwardly lying in the space between the edges of the sheets to the rearof said side edges and opening forwardly, a back strip also of sheetmetal having its edges engaging the rear faces of the glass sheets andprovided at intervals with perforations, clips slidably mounted upon theconverging sides of said dovetail portion, and securing bolts extendingthrough the perforations in the back strip and threaded at their frontends through the clips, such bolts being adapted to engage the rear faceof the dove-tail portion and hold the clips in adjusted positionslongitudinally of the dove-tail portion.

In testimony whereof, we have hereunto subscribed our names this 21stday of September, 1921.
